CHALLENGE

ArcelorMittal Hunedoara faced inefficiencies in its rolling mill lines due to fragmented technical documentation access. Workers frequently left the production floor to locate, translate, and print manuals, procedures, and work orders, taking 43 minutes to find technical documents through a cumbersome process that reduced first-time fix rates and extended repair cycles.

43 minutes to retrieve physical technical documentation
Extended repair cycles and prolonged downtime
Reduced first-time fix rates, increasing rework
Engineers leaving production floor frequently
Paper documents damaged and discarded after use

SOLUTION

Instant Knowledge Access

  • Integrates with existing systems to source and unify user manuals, procedures, spare parts and technical drawings.
  • Workers can search, view, and translate manuals in real time using mobile devices.
  • A 43-minute workflow, now under 1 minute.
  • Real-time recommendations and mobile guidance for decision-making.
